Application filed March 22, 1916. Serial No. 85,844.

To all whom it may concern: 4

Be it known that I, JOSEPHINE D. ARGHARD,

a citizen of the United States, and a resident of Yonkers, in the county of Westches- 'ter and State of New York, have invented -certain new and useful Improvements in Window-Curtains, of which the followmg P ing a window and which means also permit ventilation of a room in degrees under the control of the occupant of the room according to whether the curtain is set'for absolute privacy, entire interior exposure, or various stages therebetween.

My invention is of the louver type of closures, with the louvers in vertical arrangement in the form illustrated and which louvers are formed of fabric of desired character, material, and design, at the pleasure of'the owner or occupant of a room provided with the invention.

My invention contemplates the manufacture and sale of the louver supporting and operating means, these means comprising identical fixtures at the top and bottom of the space which it is desired to curtain, and of such simplicity as to be readily installed by any one, without the need for skill.

My invention further contemplates the provision of means for locking the louvers at desired adjustments, theselocking means being self-contained with each fixture.

My invention is fully described in the following specification, of which the accompanying drawings form a part, in which like characters refer to like parts in each of the views, and in which:-

Figure 1 is an interior view of the lower portion of a window frame provided with my invention, partly broken away to show structural features, and in full ventilating louver position; Fig. 2 is a section taken on the line 2-2 of Fig. 1, indicating a par.- tially closed louver position in dotted lines; Fig. 3 is an enlarged section taken on the line 33 of Fig. 1; and Fig. 4 is an enlarged section taken on the line 44 of Fig.1.

Referring to the drawings, 5 indicates an upper fixture and 6 a lower fixture, both being preferably identical in form and consisting, each, of two parallel horizontal rods desired length, are preferabl .7 and 8 joined by means of pivotally arranged bars 9 which permit relative movement of the rods 7 and 8 toward or from each other'though always in a state of parallelism, these bars also being in constant parallelism and, while they may be of any of from one totwo inches in length in or er not to have the fixture project too far into a room when the curtain is in full ventilating position. The bars 9 are equidistant and are spaced apart a distance slightly less than their lengths, so that each bar will extend slightly beyond the adjoining pivot which it overlies of the next successive bar, according to the direction of inclination of the bars by the movement of one rod 7 or 8 with respect to the other in either direction, toward closing positions of the louvers.

At each end of the rods 7 and 8 is a link bar 10 in pivotal connection with said rods, and the inner end of which is directed downwardly and passes through a horizontal projection 11 on a plate 12 screwed to the corresponding side of thewindow frame 13 in which the sash 14 is vertically movable. This downwardly directed end 10, for the upper fixture as shown in detail in Fig. 3, at each end thereof, is bowed toward the respective plate 12 to bear against the same, and this plate 12 is serrated, undulated, corrugated, or roughened in order to provide a frictional or binding contact between each bar end 10 and its respective plate when these link bars 10 are swung on their pivotal points in the rod 7 and respective projection 11, thus serving to lock the parts of the fixture in any adjusted osition, at the upper part of the curtain. 'Fhe link bar ends 10 and plates 12 are the same for the lower fixture 6 as for the upper fixture 5 described, but these ends 10 are upwardly directed through the projections 11 of the respectiveplates 12, whereby the rods 7 and 8 of the fixture 6 are held in the same horizontal plane against upward stress, whereas the rods 7 and 8 of the upper fixture 5 are held in a horizontal plane against downward stress.

Stitched to each pair of bars 9, the bars in vertical alinement in the two fixtures "constituting the pairs, is a strip 16 of fabric of any desired material or design though of a width equaling the distance between the rods 7 and 8 when farthest separated, or in other words the lengths of the bars 9, and p these strips hereinbefore and hereinafter referred to as louvers maintain the fixtures in relationship with each other as regards their movement out of their respective horizontal planes, although the upper or lower rod 8 may be swung toward the respective rod 7 to carry the upper or lower ends of the louvers 'into an overlapping position without afi'ecting'the rod 8 of the other fixture, the rod 8 of each fixture being manually swung independently of the other. I refer to arrange a louver in position to slightly overlie each side of the Window frame, whereby a complete closure results regardless of the direction of swinging movement of the fixtures, either to right or left hand, and because of the link rod ends 10 and the corrugations 15, or equivalents, the louvers are held at any desired adjusted angularity. By this louver arrangement it will be seen that I may provide entire privacy or secure the entire ventilating capacity of the window opening, or any stages therebetween, and at the same time provide an ornament to a room.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. A window curtain, comprising upper and lower fixtures each of wh1ch consists of two parallel rods, and a plurality of spaced bars in pivotal connection with said rods, a plate secured to the window at each end of one of said rods provided with a perforated projection serving as a rest for said last named rod, a link bar in pivotal connection with said rods and provided with a vertical section passed through the perforation in said plate projection, and flexible strips joining'the respective bars of both fixtures;

2. A window curtain, comprising upper and lower fixtures each of which consists of two parallel rods joined by spaced bars in pivotal connection therewith, a plate at each end of one of said rods and secured to said window, said plate having a perforated projection thereon and having a roughened surface, a link bar in pivotal connection with said rods and rotatable in said rojection, said-link bar being curved to ear on the roughened surface of said plates to prevent movement of said rods with respect to each other, and flexible strips joining the respective bars of both fixtures.
